Vulnerability from fkie_nvd - Published: 2026-05-08 15:16 - Updated: 2026-05-20 18:32

Severity

7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

Summary

In the Linux kernel, the following vulnerability has been resolved: usb: renesas_usbhs: fix use-after-free in ISR during device removal In usbhs_remove(), the driver frees resources (including the pipe array) while the interrupt handler (usbhs_interrupt) is still registered. If an interrupt fires after usbhs_pipe_remove() but before the driver is fully unbound, the ISR may access freed memory, causing a use-after-free. Fix this by calling devm_free_irq() before freeing resources. This ensures the interrupt handler is both disabled and synchronized (waits for any running ISR to complete) before usbhs_pipe_remove() is called.

If an\ninterrupt fires after usbhs_pipe_remove() but before the driver is fully\nunbound, the ISR may access freed memory, causing a use-after-free.\n\nFix this by calling devm_free_irq() before freeing resources. This ensures\nthe interrupt handler is both disabled and synchronized (waits for any\nrunning ISR to complete) before usbhs_pipe_remove() is called."
